JOH/V Afa/V5? UFS MD A'ITD RN EYE SINK RIM John Homer Opstad, Austin,Application August 2, 1955, Serial No. 525,866 i 1 Claim. (Cl. 4 187)This invention relates to devices for installing kitchen sinks,washtubs, and the like in openings in tops of kitchen cabinets, panels,and the like, and in particular, a rim having a flange extended over theadjoining portion of the panel or top and another llange extended overthe rim of a sink or the like and a clamp having an extended screw forurging the llanges of the rim downwardly upon upper surfaces of thepanel and flange of the of the sink whereby a thumb nut on the lower endof the screw extended from the clamp is adapted to be rotated to securethe parts in assembled relation from a point below the lower part of thesink so that a plumber or other workman is not required to work in theclose quarters usually provided between the walls of a sink or tub andcabinet. Y

The purpose of this invention is to facilitate installing kitchen sinks,washtubs, and the like whereby rims of such devices are adapted to beclamped in openings of panels or tops of cabinets from points belowlower surfaces of the sinks or tubs so that the workmen may operate incomfort.

In conventional sink installations, comparatively narrow spaces areprovided between outer surfaces of the bodies of sinks and adjoiningsurfaces of cabi-nets or stands in which the sinks are installed and itis very difficult to operate a wrench or screwdriver in such areas. Forthis reason comparatively crude joints are formed between rims of sinks,tubs, and the like and panels or tops of cabinets in which the devicesare positioned and surfacing materials used in combination with thepanels or tops around sinks or tubs soon bulge, split, or disintegrate.With this thought in mind, this invention contemplates a clamp for a rimadapted to be positioned around a sink, tub, or the like in which theclamp is provided with an elongated screw or bolt whereby the parts areadapted to be clamped in assembled relation from a remote point, such asa point positioned below the lower surface of the sink -or tub.

The object of this invention is, therefore, to provide means for forminga rim for a sink, tub, or the like wherein the clamping elements areadapted to be actuated in comparatively open areas spaced below theconnecting portions of a sink and panel or top.

Another object of the invention is to provide an improved rim for a sinkor the like in which the rim is adapted to be used in combination withsinks, tubs, and such devices now in use.

A further object of the invention is to provide a rim for sealing ajoint between a sink or tub and the top or panel of a cabinet in whichthe sink or tub is positioned wherein clamping elements of the sealingmeans are adapted to be actuated from a point spaced below the joint inwhich the device is of a simple and economical construction.

With these and other objects and advantages in view, the inventionembodies a substantially at arcuate rim States arent" O 2,820,229Patented Jan. 21, 1958 ICC 2 having ya Web with a bead on the lower edgedepending therefrom with an elongated bolt having a gripping linger onthe upper end adapted to be positioned over the bead with a griping jaw,a spacing tube and a thumb nut positioned on the bolt and with the jawprovided with a set screw for adjusting the position thereof tocorrespond with the panel or cabinet top.

Other features and advantages of the invention will appear from thefollowing description, taken in connection with the drawing, wherein:

Figure 1 is a front elevational view of a kitchen cabinet with partsbroken away showing the installation o-f one side of a sink in thecabinet with the rim of the sink clamped in position with an arcuatemolding or rim and with lianges of the arcuate molding or rim clampedagainst the upper surfaces of the cabinet top and rim of the sink with athumb nut, spacing tube and jaw on an elongated bolt depending from themolding or rim.

Figure 2 is a cross section through the joint taken on line 2 2 ofFigure 1 with parts o-f the clamping element shown in elevation and withother parts broken away.

Figure 3 is a plan view of a connectio-n at the round corner of a sinkshowing a modification wherein the elongated bolt is omitted and theparts are retained in position with a set screw.

Figure 4 is a cross section through a rim of a sink or tub taken on line4 4 of Figure 3 showing the elongated bolt of the clamp turned to aposition to facilitate installing lingers at the upper end of the bolton the bead of the rim in full lines and with the bolt turned to aposition for use in broken lines.

Figure 5 is an exploded view of the improved sink rim with the parts asshown in Figure 1, the parts being separated and spaced below the joint.

Figure 6 is a sectional plan taken on line 6 6 of Figure l showing thelower gripping jaw of the clamp.

Figure 7 is a cross section taken on line 7 7A of Figure 3 showing amethod of temporarily clamping an arcuate or round corner of a rim inposition on a sink as the sink is being installed in a cabinet or thelike.

Referring now to the drawing, wherein like reference characters denotecorresponding parts, the improved sink rim of this invention includes anarcuate rim 10 having extended anges 11 and 12 with a depending web 13having a bead 14 on the lower edge, a bolt 15 having a linger 16 on theupper end for gripping the bead 14 of the web 13, a wing or thumb nut 17adapted to be threaded on the lower end of the bolt 15, a coactinggripping jaw 18 have an opening 19 therein to receive the bolt 15 andhaving a set screw 20 threaded in the base thereof, and a spacing sleeve21 adapted to be positioned on the bolt 15 and adapted to be urgedagainst the jaw 18 by the nut 17.

With the parts as illustrated in Figure 1, the ange 11 of the rim 10 ispositioned upon an edge of a panel or top 22 of a kitchen cabinet 23 andthe llange 12 on the opposite side of the rim is positioned upon aliange or rim 24 of a kitchen sink, as indicated by the numeral 25, andwith the parts assembled, wherein the linger 16 is extended around thebead 14 and the jaw 18 positioned against the under surface of the panelor top 22 the nut 17 is actuated from a point below the sink whereby theparts are clamped in position, securing the sink in the opening in thepanel or top of the cabinet.

With the adjusting or set screw 20 threaded in the base or heel of thejaw 18 and with the jaw urged upwardly by the nut 17 and sleeve 21, theposition of the jaw in relation to the flange 11 on the rim or moldingstrip is readily adjustable to compensate for panels or 3 cabinet tops,such as the member 22, of different thicknesses.

In making installations, the rim is temporarily held to the sink by afastener, as illustrated in Figure 3, wherein an inner clip angle havinga horizontally disposed leg 26 and a vertically disposed leg 27 may beused with the corner of the clip angle resting upon the upper surface ofthe head 14 at the lower edge of the web 13 of the rim and with anadjusting screw 28 threaded in the horizontally disposed leg 26.

The clamping ring illustrated in Figure 1 may be used at major points atthe sides and ends of a sink, tub, or the like and the clip angleillustrated in Figure 7 may be used at the corners to retain the partsin assembled relation as the other fasteners are being installed. Bythis means a substantially at arcuate rim 10 is adapted to be positivelysecured by clamping elements continuously around a sink, washtub, or thelike.

Although the sleeve 21 is illustrated as being comparatively short, itwill be understood that the length of the sleeve is adapted to beextended so that a plumber or mechanic may readily grip the nut 17 atthe lower end of the threaded rod from a point below a sink or washtub.By this means the clamping elements may be adjusted to secure the partsin assembled relation without the inconvenience of operating a wrench orscrewdriver in the narrow space between the side walls of a sink orwashtub and a wall, such as the wall 29, of a cabinet or the like. v

With a sink or the like positioned in an opening, such as the opening30' of a kitchen cabinet, top or panel, the web 13 of the rim 10 isdropped downwardly through the slot between the edge of the ange 24 ofthe sink and the edge of the top or panel and with the rim in positionthe rod 15 is inserted with the finger 16 thereof which is ilat in crosssection positioned over the bead 14 and with the jaw 1S retained on therod with the sleeve 21. The rod 15 extends through the opening 19 of thejaw, the opening 19 being rectangular shaped and the rod 15 having atsides 31 to prevent turning of the jaw on the rod whereby with the setscrew 20 positioned to hold the upper surface of the jaw 18 against theunder surface of the top or panel 22 the thumb nut 17 may be threaded onthe lower end of the rod 15 to positively clamp the parts in assembledrelation, as shown in Figure l.

The parts may be provided in diierent sizes to accommodate diiferenttypes of installations and the parts may also be formed of non-corrosivematerials or of coated or galvanized materials as may be desired.

It will be understood that modifications, within the scope of theappended claims, may be made in the design and arrangement of the partswithout departing from the spirit of the invention.
